Atomic model sets are hands-on educational tools used in schools and labs to visualize complex chemistry concepts like atomic structure, molecular geometry, and chemical bonding (single, double, triple bonds) by building 3D representations of atoms and molecules, aiding understanding in organic/inorganic chemistry, and serving as classroom/lab displays. 

Chemical rubber gloves create a vital barrier, protecting hands from harmful substances like acids, solvents, oils, and biohazards in industries from healthcare and labs to manufacturing and cleaning, preventing burns, irritation, and infections while allowing dexterity for tasks like handling chemicals, maintenance, and food prep. Materials like nitrile, neoprene, and butyl are chosen based on the specific chemical, with applications ranging from general household cleaning to handling harsh petrochemicals, requiring different levels of protection, dexterity, and reusability. 

Porcelain mortars and pestles are versatile tools for grinding, crushing, and mixing solids into fine powders or pastes, essential in kitchens for spices (curry pastes, pesto, guacamole), pharmacies for compounding medicines (trituration), and labs for sample prep (chemicals, pigments, dental materials). Their non-porous, chemically resistant surface ensures purity, while the rough interior and pounding action release flavors better than blenders, preventing heat-induced oxidation and preserving potency. 

A Petroleum Density Kit is used in the oil & gas industry, fuel stations, and labs to accurately measure the density of fuels (petrol, diesel, lubricants) using hydrometers, thermometers, and jars, ensuring quality control, performance, and compliance with ASTM/IP standards by checking for contaminants (water/oil) and verifying fuel efficiency. 

Laboratory gas taps control the flow of various gases (like natural gas, nitrogen, oxygen, hydrogen) for heating (Bunsen burners), running analytical equipment (GC, MS), combustion, purging, and specialized experiments, offering precise, safe delivery for functions from simple flame work to complex thermodynamics, often featuring color-coding and safety features for different gas types. 

A spirit lamp (or alcohol burner) is a small lab device using alcohol fuel (like ethanol) and a wick to create a controllable flame for gentle heating, sterilizing small tools, or performing basic chemistry experiments like flame tests, offering a clean, portable heat source for general lab work, schools, and clinics when high-precision heating isn't needed. Key safety involves using proper fuel levels, extinguishing with the cap, and never refueling a burning lamp.  

Laboratory porcelain wares are essential for high-temperature applications like heating, melting, and calcining, as well as for chemical resistance, used in crucibles, evaporating dishes, mortars, and funnels for tasks such as evaporating solvents, mixing solids, and conducting reactions where glass or plastic would fail, ensuring sample purity due to their inert nature. 

A laboratory thermometer is used to measure the boiling point and freezing point during science experiments. It is also used to measure the temperature of substances. It measures temperature ranging between -10 degree Celsius and 110 degree Celsius.

Glass alcohol thermometers are used for measuring low to moderate temperatures in labs, schools, homes, and cold environments (like freezers) because alcohol has a very low freezing point, making them a safer, less toxic alternative to mercury, ideal for general science, weather (minimum temps), and processes needing precision in cold ranges. 

Lab wall thermometers are commonly used in a variety of laboratory procedures, including material testing, environmental monitoring, and research. They are also used in industrial, agricultural, and medical settings to monitor temperature changes in equipment, systems, and environments.

Product Detls: Capacity 3.5 L Usage/Application Laboratory Material Polycarbonate, Aluminum Shape Round Automation Type Semi-Automatic The lid of the jar is made of Aluminum pressure die Casting fitted with Pressure Valve, Vacuum Valve, Safety Valve & compound Pressure cum vacuum gauge, three finger aluminum clamp and sealing "O" ring. This is recommended only where inside r of jar is removed thru vacuum pump and CO2 is filled in the jar thru CO2 gas cylinder to generate anaerobic condition in the jar. Also supplied with pln aluminum pressure die casted lid which can be fitted when readymade gas packs are used to generate the anaerobic conditions inside the jar. When readymade gas packs are used, there is no need of lid fitted with dial gauge etc., for extra life of equipment.
